Interface is looking good, but here are a few things I noticed in the first 10 minutes of messing around:
1. When the project folder has subfolders, the interface defaults to the object palette instead of the file palette, which may confuse people. It almost had me thinking subfolders were not supported. lol
2. Clicking the timeline does not actually display the current frame number. I have to drag the bar to update that number.
3. Old SCML files do not seem to load at all, and there are no visible feedback messages. It should at least pop-up a "Current version does not load projects" message.
4. Loading a new SCML file that you just saved will crash the application every single time regardless of what you saved. I tried saving just 1 frame with 1 object, then 2 objects, then 2 frames with 2 objects, nothing loaded, crashed every time.
Some good things, though:
1. Delete key actually works on the timeline now. I can finally delete frames again! I was unable to do so in later alpha versions.
2. Background color options are superb. I love customizing and tinkering with settings. You should add some options for that grid line
3. Most of the old features remain unchanged and very familiar to me. Change is good, but I like that it's not completely alien.
Some other personal requests:
1. Middle-click the canvas area to pan the view. I hate dragging scroll bars. Granted not many people will need this feature, and I probably won't, neither.
2. Right-click the canvas for grid and snap options. At least put then in the file bar options somewhere. I would like, for example, to turn off the center line.
Good work so far. I hope the application continues to progress and eventually rivals Spine as a stable and feature-rich, object-oriented animation tool.
